If Proxy "ownKeys" trap is missing, keys are sorted by type in ascending
chronological order.
info: |
Object.getOwnPropertyDescriptors ( O )
[...]
2. Let ownKeys be ? obj.[[OwnPropertyKeys]]().
[...]
4. For each element key of ownKeys in List order, do
a. Let desc be ? obj.[[GetOwnProperty]](key).
[[OwnPropertyKeys]] ( )
[...]
6. If trap is undefined, then
a. Return ? target.[[OwnPropertyKeys]]().
OrdinaryOwnPropertyKeys ( O )
[...]
3. For each own property key P of O such that Type(P) is String and P is
not an array index, in ascending chronological order of property creation, do
a. Add P as the last element of keys.
4. For each own property key P of O such that Type(P) is Symbol,
in ascending chronological order of property creation, do
a. Add P as the last element of keys.
5. Return keys.
